摘　　要：目的 :探讨运用滑动征判断进展期胃癌侵及胰腺的诊断价值。方法 :观察胃肿块和胰腺间的相互运动情况。在深呼吸时当胃肿块沿胰腺表面全部滑动或虽部分滑动但胃和胰腺间脂肪层存在时 (滑动征阳性 ) ,认为没有胰腺受侵 ;当胃肿块沿胰腺表面没有滑动或有部分滑动但胃和胰腺间脂肪层破坏时 (滑动征阴性 ) ,则认为胃癌侵及胰腺。随后把超声判断结果与术中探查结果和术后病理所见进行对比分析。结果 :在 3 5例患者中 ,15例有胰腺受侵 ,2 0例胰腺未受侵及。超声运用滑动征诊断胰腺受侵的敏感性为 87% ,特异性为 90 % ,准确性为 89%。结论 :运用滑动征判断进展期胃癌侵及胰腺是简单和高度准确的。Objective:To assess the value of the sliding sign on sonograms in evaluating direct pancreatic invasion of advanced gastric carcinoma.Methods:Sonography can directly detect the motion between the gastric mass and the pancreas.When the gastric mass show complete sliding motion against the pancreas or partial motion with a preserved echogenic fat plane between the two organs on full respiration(positive sliding sign),patients were considered to have no pancreatic invasion.When the gastric mass had no sliding motion against the pancreas or partial sliding motion with a disrupted echogenic fat plane between the two organs(negative sliding sign),patients were considered to have pancreatic invasion.The results of sonography were compared with the findings at surgery and pathology.Results:Of the 35 patients,15 had pancreatic invasion and 20 had no pancreatic invasion at surgery and pathology.The sliding sign on sonography yielded an 87% sensitivity,90% specificity and 89% accuracy for the diagnosis of pancreatic invasion.Conclusions:Application of the sliding sign on sonography was simple and highly accurate in the diagnosis of pancreatic invasion by advanced gastric carcinoma.
